Abstract

The studies were conducted in different parts of the Baikal Region - Southern Prebaikalia, South-Western Transbaikalia, and Northern Prebaikalia. It was shown that the biogeographical conditions have a greater effect on alteration of the trends of chemical elements concentrations, while they exhibit smaller changes in different forest types in the same geographical region. However, the most significant factor causing misbalance of the majority of elements is the emission load. It is concluded that the investigation of the trends of elements contents in assimilating organs of trees serves as the most important link in the system anаlysis of the vital state of tree stands under natural conditions and under the action of abiotic factors.
